Non-Hermitian phenomena offer a novel approach to analyze and interpret spectra in the
presence of interactions. Using the density-matrix renormalization group (DMRG), we …

Doublon-holon dynamics is investigated in a pumped one-dimensional Hubbard model with
a staggered on-site Coulomb interaction at half-filling. When the system parameters are set …

We have examined the behavior of the compressibility, the dc conductivity, the single-
particle gap, and the Drude weight as probes of the density-driven metal-insulator transition …

We calculate ground-state energies and density distributions of Hubbard superlattices
characterized by periodic modulations of the on-site interaction and the on-site potential …

We show that a tight-binding one-dimensional chain composed of interacting and non-
interacting atomic sites can exhibit multiple mobility edges at different values of carrier …

We study the metal-insulator transition in one-dimensional Hubbard superlattices, modeled
by a repeated pattern of repulsive (ie, positive on-site coupling) and free sites. The evolution …

We discuss how entanglement of strongly correlated fermions is influenced by a superlattice
structure by considering a one-dimensional Hubbard superlattice, made up of a repeated …

We use numerically unbiased methods to show that the one-dimensional Hubbard model
with periodically distributed on-site interactions already contains the minimal ingredients to …

We consider fermions in one-dimensional superlattices (SL's), modeled by site-dependent
Hubbard-U couplings arranged in a repeated pattern of repulsive (ie, U> 0) and free (U= 0) …

We study the formation of charge density waves (CDW's) in one-dimensional Hubbard
superlattices, modeled by a repeated pattern of repulsive (U> 0) and free (U= 0) sites. By …
